Nature in Action and Beautiful Foliage

LIVING PLANET

What happens when an ecologist from
Australia, packs up and leaves to work in Namibia for a couple of years?

Namibia wildlife

Some of the wildlife found in Namibia are big cats, Cheetahs, Elephants, Zebras, and Giraffes.Let’s find out.. I'm talking with Katie Oxenham, a Consulting ecologist who now lives in Sydney.

Katie's role in Namibia was conservancy and natural management support. She was employed by the Namibia Nature Foundation and worked with communities in the north of the country to manage natural resources such as the harvest of Devil's Claw. Devil's Claw is different to the Australian weed by the same name found in the Top End.

Help with how to sustainably harvest the Devil's Claw was important because it prevented the plant from becoming regionally extinct. Katie also helped the indigenous population with entering into contracts with private companies of eco-tourist lodges whereby they would acquire jobs thus giving them a reason to conserve wildlife.Namibia has unique landscapes and is home to a vast diversity of wildlife found nowhere else on Earth.There are approximately 4,000 plant species, over 650 bird species and 80 large mammal species.Namibia is a pretty special place
and a must see destination for tourists wanting to see African wildlife.

VEGETABLE HERO

ROMANESCO BROCCOLI

Which vegetable has more vitamin C
than an orange?

Broccoli, Brassica oleracea var Italica or botrytis cymosa?

Earlier this year I mentioned that Broccoli
heads are actually groups of flower buds that are almost ready to flower?

Each group of buds is called a
floret.

That’s still true, nothing’s
changed.

Broccoli is of course in the
Brassicaceae family of vegetables along with cauliflower, cabbages, Brussels
sprouts, turnips and many of the Asian greens.

Just to remind you why should you grow any type of Broccoli if it’s
available all year round in your supermarket?

Firstly, supermarket Broccoli has
probably been sprayed for all manner of pests whether or not the pests visited
the Broccoli plant.

Secondly, supermarket Broccoli stems
are pretty tough to eat, when they’re supposed to be tender.

Why, because that type of Broccoli
transports better?

Homegrown Broccoli, especially the
heirloom varieties, also re-shoot after your cut of the central Broccoli stem.

Plus, Broccoli is pretty easy to
grow.

Finally, to taste great, broccoli
has to be properly cared for and must also be picked at the right time.

If you just buy broccoli at the
green grocer’s, the broccoli may look great but the taste may not be up to scratch.

How so? They may have been picked
before becoming fully-mature.

Or they may have been picked at the
right time but then stored too long

With home-grown broccoli, you can
also be sure how it has been grown:

You know exactly where it has come
from, what you used to grow and protect it, unlike those sold in supermarkets
and even in farmer’s markets.

Today’s Broccoli is the Romanesco broccoli or some call it roman
cauliflower

You might think this lime green
cauliflower come broccoli is a new invention but it’s been around since the 16th
century.

The reason why broccoli is making an
appearance in this segment is that even though it’s called Romanesco broccoli
it’s much more crunchy than either broccoli or cauliflower.

The flavour is different as well,
some say nutty even, while others say it tastes like a cross between broccoli
and cauliflower.

That seems too hard to imagine.

To add to the confusion, apparently
the French call it Romanesco cabbage and the English called it Italian
asparagus.

So it’s a mixed up vegetable if you
like but the most fascinating part of Romanesco is its appearance.

Much has been said about the
mathematics of this spiral pattern, a lot of which is fairly complex.

Its spiralled buds form a natural
approximation of a fractal, meaning each bud in the spiral is composed of a
series of smaller buds.

You might’ve heard of the Fibonacci
sequence?

The spirals follow the same
logarithmic pattern.

Plus it’s a very attractive
vegetable to be growing in the garden.

Where did it come from?

Romanesco is a unique Italian variety
of broccoli with a yellowish-green dense head that forms an unusual spiral
pattern.

How to grow Romanesco Broccoli?

Sow the seeds of Romanesco broccoli
in from February July in arid zones, March through to August in sub-tropical
areas, Spring and Autumn in temperate zones,

And cor cooler regions, you’ll have to wait
until October before sowing.

The plants need the same care as
either Broccoli, or cauliflower and that is they’re not too choosy about the
site they’re growing in but prefers to be in full sun, but also will tolerate
partial shade with no problems.

Growing in too much shade will
reduce the size of the Broccoli head.

The ideal soil is a reasonably heavy
(not pure clay) which is rich in nutrients and has been well-dug.

Like all brassicas, Broccoli needs a
minimum soil pH of 6; but really prefers a pH of 7.

Add lime if you need to raise the
soil pH.

Broccoli is what’s called a heavy
feeder, so do add plenty of blood and bone, and decomposed manures by the
bucket load before you start.

Sow your Broccoli seed about 2 mm
deep, and space the seedlings about 40cm apart so they don’t crowd each other.

Harvest broccoli heads when they
have reached maximum size, are still compact, and before the buds loosen, open
into flowers, or turn yellow.

It will be about 70-100 days or 2 ½
-4 months, when your Broccoli will be ready if you plant it now.

When do you pick your Romanesco Broccoli?

You’ve got to time it just right,
and that’s when the cluster of tight buds in the central head is well formed
and before the individual flowers start to open.

Make a sloping cut (this allows water
to run off), picking a piece that's about 10 cm long.

That way you’ve left a reasonable
amount of the plant intact to produce smaller sideshoots or
"florets," which you can pick as well.

Great for stir fries.

At this stage, don’t stop feeding
and watering the remaining broccoli stem otherwise your plants will go to seed
and you won’t get any side shoots.

TIP: If your Broccoli plants starts
to flower it’ll going into seed production and you won’t get any more side
shoots.

Why is any type of Broccoli good for you?

Broccoli contains twice the vitamin
C of an orange.

Did you know that just 100g of Broccoli
has two day’s supply of vitamin C (don’t overcookor you’ll lose some).

Broccoli also a good source of
dietary fibre, potassium, vitamin E, folate and beta carotene

100g broccoli has 120kJ.

Broccoli also contains magnesium and
as much calcium as whole milk.

One cup of broccoli boosts the
immune system with a large dose of beta-carotene.

Great for preventing colds. Don’t
underestimate the power of broccoli! THAT

DESIGN ELEMENTS

Update Your Garden with Different Foliage.Do flowers play the starring role
in your garden, while the greenery gets relegated to backstage?

Foliage makes a garden. photo M Cannon

The greenery, or foliage if you
like, are the mainstay of gardens and garden design because they’re there all
year when the flowers fade.

Think of the delicate fronds of
ferns or the fountain like effects of many types of ornamental grasses. The
leaves of these plants don’t just serve as a lovely background for flowers,
because they have their own attraction. There are some really beautiful
foliaged plants that could be used as a dominant feature alongside your
flowers. Remember, foliage will carry your garden through all seasons, long
after the flowers have faded away. I'm talking with garden designer Louise McDaid.

If doesn’t hurt the pocked to
update your garden in this series, because we’re not doing the crazy make-over.

There should be plenty of ideas to
get you thinking about updating the foliage in your garden.

PLANT OF THE WEEK

Sandpaper Fig Ficus coronataBush tucker plants are one of the
hot trends in horticulture and this one is no exception.

Ficus coronate Sandpaper Fig

What about a tree that has leaves
the not only feel like sandpaper, but can be used for sandpapering surfaces.

Let’s find
out more about this plant by listening to the podcast.
I'm talking with the plant panel, Karen Smith, editor of Hort Journal www.hortjournal.com.auand Jeremy Critchley, The Green Gallery wholesale nursery owner. www.thegreengallery.com.au

Ficus coronata is a food
plant for the caterpillars of the Queensland butterfly the common- or purple
moonbeam. One of many host plants for the larvae of the Common Crow (Euploea
core).

Good jam fruit but fussy to prepare
because of hairs on skin.

Suited to a shady position in
gardens, or medium to brightly lit indoor spaces. Like all figs in garden
situations, they attract birds such as species of silvereye and rainforest
pigeon.

Of the 1,000 fig species, most are
tropical and 70 per cent of the animal life in the rainforest depends on them.

They are a “keystone” species: no
figs, no jungle. Birds, bats, monkeys, gibbons, insects – all run on figs.

They are sweet – which means they
are high in energy – and the trees can fruit/flower several times a year.

Aboriginal Women: Would use the
leaves to "sand" there feet and nails.

Men: Would use the leaves to do the
fine sanding of important artefacts and weapons.
